'Due to...' implies one and only one cause. e.g., 'Due to the recent economic crisis there will be no Christmas bonuses this year.' To me, it sounds awkward to say 'Due to the recent economic crisis and the embezzlement of funds, there will be no Christmas bonuses this year.' Personally, I don't speak or like the phrase 'due to'. There are people who tend to overuse this phrase repeatedly when they could simply state the facts: 'Because of the recent economic crisis...'.
